Display screen with an animated graphical user interface



FIG. 1 is a front view of a first image in a sequence of a display screen with an animated graphical user interface showing our new design; and

FIG. 2 is a second image thereof.

The appearance of the animated graphical user interface sequentially transitions between the images shown in FIGS. 1 and 2. The process or period in which one image transitions to another forms no part of the claimed design. The broken line showing of portions of the display screen with an animated graphical user interface forms no part of the claimed design. 

CLAIM The ornamental design for a display screen with an animated graphical user interface, as shown and described.
